I've worked a lot to fix all the possible bugs of this library. Anyway I'm not sure DirectQB is totally bug-free. The main "bug" I've found is with the mouse initialization when calling DQBinit. Sometimes on my K6-200 it locks up the machine, and you have to reboot; this seems not to happen on my notebook with external mouse (Logitech), so I'm supposing it's a mouse driver problem, also because theoretically my code should work... Again about the mouse, I've reported that the hotspot setting when calling DQBsetMouseShape fails under Windows 95: to obtain the correct X hotspot coordinate you must multiply your value by 2 and then pass it to the function. This is very strange as all works ok when running the same code under plain DOS, so I've not fixed it. I've not found any more bugs on the library as by now; if you find others, please let me know, and I'll try to fix them.
